METHOD FOR REPLACING A RAIL FOR GUIDING A PIECE OF EQUIPMENT INSIDE A NUCLEAR REACTOR

Method for replacing a rail for guiding a piece of equipment inside a nuclear reactor. The method comprises the following steps: creating a fixed coordinate system (68); determining the coordinates of an origin circumferential position of uncontaminated areas (60, 62, 64) of the original rail (26) w...

Zusammenfassung:Method for replacing a rail for guiding a piece of equipment inside a nuclear reactor. The method comprises the following steps: creating a fixed coordinate system (68); determining the coordinates of an origin circumferential position of uncontaminated areas (60, 62, 64) of the original rail (26) with respect to the fixed coordinate system (68); and circumferentially positioning a replacement rail (90) using the origin circumferential position of the uncontaminated areas (60, 62, 64).
